information about Sign Posts

Aluminium posts have a smoother, more polished finish compared to steel posts and are about 3 times lighter. Aluminium posts are used more frequently where appearance and weight is of greater importance.
Steel Posts are finished in a textured grey plastic coating and are generally used for industrial applications such as highway signs, and where larger panels are to be used. Steel posts are about 3 times heavier than aluminium posts.
Wide base posts are used when road signs require illumination to be added. The base of the post is wider to accomodate electrical fittings.
